You won't worry about tossing and turning when you're zipped into the luxurious comfort of the Big Agnes Women's Lulu 15 Sleeping Bag. It provides three season versatility with its Isotect Hotstream insulation. This recycled polyester fill mimics the lofty warmth and luxurious plushness of its down counterparts, but without sacrificing heat retention in damp conditions. The bag's sculpted contour wraps around your body like a cocoon for greater warmth on those cold evenings under the stars. One of the Lulu's best features is the full length pad sleeve, which promotes a stable sleeping interface that won't slip and slide around. The pad sleeve has a stretch panel for a dedicated camp pillow. If you're traveling light, you can even stuff a bunch of clothes inside and create your own makeshift pillow. For greater heat retention, the no draft collar, wedge, and zipper lock in precious warmth when others are shivering inside their bags. Another innovative feature, the Free Range Hood provides freedom to lift and turn your head with the hood fully cinched.
